I'm not a bluetooth expert but the way I understood it, an application can implement a serial port profile and use the bluetooth stack even if the stack itself doesn't offer the serial profile.
I can confirm that the WayFinder software works fine with a Bluetooth GPS receiver connected to the 6630. But applications that simply try to open a serial port on the phone will not find any.

I think not having a bluetooth serial profile is another design decision that Nokia took to please network operators; this way you can't use your phone to connect to a pc and access the internet using the pc as a gateway.

Yes, I think it's possible. One phone based on the Windows Mobile platform suffered from the same problem and someone wrote an application to enable the serial profile. I am not aware of anyone trying the same thing for a Symbian phone.

So, what's going on? Is it to do with the WIDCOMM Bluetooth stack I'm using? Or have Nokia engineers been sniffing too much ketamine the last year?

Hi fannypad, ControlFreak actually works fine on a 6630. In fact that's what i use it on everyday

You don't need the phone to support incoming serial port profile connections since ControlFreak works by creating a connection from the phone to the PC, not the other way around. So all you need to do is open the WIDCOMM bluetooth configuration and make sure the Bluetooth serial port is enabled in Local Services and then set that COM port number into the winamp plugin configuration. Choosing Connect from the phone application will create the Bluetooth connection and everything should work fine.

but if these apps support a BT serial connection, it should be possible to use a program which can connect through BT, giving you internet through BT !

I've considered using Gnubox for internet access via bluetooth on my N70 but am concerned that the access point changes will affect how I use other applications or 'standard' access points.

So I thought I would bump this thread ... ControlFreak is excellent and works perfectly e.g. as a WinAmp remote. I noticed the mtvoid guys (controlfreak developers) on this thread and someone else wondering why their method could not be used for internet access also e.g. with browser, RSS, IM, VOIP, etc. - anybody have any ideas?

Now, someone did say that there is possibly an application for Windows Mobile phones (I have WM6) that would allow you to open the Bluetooth Serial Port from the Phone Side. Does any have a link or a name of what this application would be?
Because i have the issue that i know many others have and are disappointed with is that your phone's chip can do everything bluetooth, but the software that is preprogrammed into the SmartPhone locks out certain features. I would like to be able to hook my Bluetooth GPS device to my Bluetooth enabled phone. And since my phone only takes Mini SDs, i can't hook up a SD GPS reciever to it. So there is plenty more i know my phone can do, and to have the right apps would help, its just the issue in finding the apps.
